[...snip] a nearly glue-less way to mount pearls on posts, although I always use epoxy as well. The post should be a snug fit and slightly shorter than the hole drilled in the pearl. Cut a slot in the top of the post and insert a wedge of (the post's) metal into the top of the slot. Put the pearl onto the post; the wedge will be forced down into the slot as you press the pearl down on the post. The wedge spreads the sides of the slot so that they expand against the sides of the hole. This method does not allow for later removal of the pearl - the metal must be drilled out.
I’m about to tackle this method. Does anyone have any other
comments/experience/etc to add? I’d be eternally grateful.
It seems to be a one-hit method, that is, no chanve of a dry run to
check how long the post ought to be.
And I assume the hole will need an internal flare.
